Osterizer

It has been claimed to be the first mainstream brand of blender,[1] though technically the Waring blender brand was introduced in 1937.

In 1946, Oster acquired the Stevens Electric Company, which had received a patent on the liquifying blender in 1922.

Oster itself was bought by Sunbeam Corporation in 1960.

Osterizer blenders tended towards heavy construction and motors.

While this raised cost, many early-model Osterizers still function today, and are more powerful than a majority of contemporary consumer blenders.
